BadSqlGrammarException:PreparedStatementCallback; SQL语法错误,当我给时间戳记参数

问题描述 投票:0回答:1

在我的Java应用程序中,我曾经有一个如下的sql查询:

INSERT INTO "KPI_MEASURE" (
        id,
        created_at,
        kpi_project_id,
        kpi_frequency_id,
        kpi_metric_id,
        branch,
        value
    )
SELECT
    nextval('"KPI_MEASURE_ID_seq"'::regclass),
    now(),
    kpi_measure.kpi_project_id,
    kpi_measure.kpi_frequency_id,
    kpi_measure.kpi_metric_id ,
    kpi_measure.branch ,
    sum(kpi_measure.value)
FROM "KPI_MEASURE" kpi_measure
    INNER JOIN "KPI_METRIC" kpi_metric                      ON kpi_measure.kpi_metric_id = kpi_metric.id
    INNER JOIN "KPI_PROJECT" kpi_project                    ON kpi_measure.kpi_project_id = kpi_project.id
    INNER JOIN "KPI_AGGREGATION_PROJECT" kpi_agg_project    ON kpi_project.name = kpi_agg_project.child_project_name
    WHERE kpi_metric.aggregated = false
GROUP BY kpi_measure.branch, kpi_measure.kpi_metric_id, kpi_measure.kpi_project_id, kpi_project.name, kpi_measure.kpi_frequency_id;

我用jdbcTemplate.update执行了该sql,并且有效。但是最近我通过一个参数更改了now()的值::today_date,我在代码中加上了该参数:

Map<String, Object> parameters = new HashMap<String, Object>();
parameters.put(TODAY_DATE, today); // TODAY_DATE = today_date

jdbcTemplate.update(sql, parameters);

但是现在,它创建了一个错误:

org.springframework.jdbc.BadSqlGrammarException:PreparedStatementCallback;错误的SQL语法...嵌套的异常是org.postgresql.util.PSQLException:未安装hstore扩展。

我不知道为什么会出错,因为当我们要在jdbc查询中添加参数时,这是我被告知要做的事情。


编辑:

列数据类型为timestamp without time zone,而today变量为String类型。我想我应该使用Timestamp,所以我更改了代码:

Map<String, Object> parameters = new HashMap<String, Object>();
parameters.put(TODAY_DATE, new Timestamp(System.currentTimeMillis())); // TODAY_DATE = today_date

jdbcTemplate.update(sql, parameters);

现在我只有这个错误

“ PSQLException:未安装hstore扩展。”

也许,我需要添加一个hstore,但是我似乎不明白为什么。

并致电jdbcTemplate.update(sql, new Timestamp(System.currentTimeMillis()));
